Sikafloor 2540 W is a solvent free, two component, water dispersed, coloured epoxy coating. It provides a protective surface treatment for concrete floors and walls exposed to light and medium use.

Suitable areas of application:

  • Industrial areas.
  • Abattoirs.
  • Water treatment plants.
  • Workshops.
  • Food processing areas.
  • Manufacturing areas.
  • Laboratories.
  • Storage areas.
  • Breweries.
  • Tunnel walls.
  • Decontamination areas.
  • Cleanrooms.


The cementitious substrate should be sound and of sufficient compressive strength (minimum 25 N/mm²) and pull off strength (minimum 1.5 N/mm²). The surfaces must be dry and free of all contaminants, e.g. oils, grease, surface treatments and coatings, etc. The substrate must be prepared mechanically to achieve an open textured fine gripping surface, free of cement laitance. Weak concrete should be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed, preferably by brush and vacuum, from all surfaces before application of the coating. Prior to application, confirm substrate moisture content.
